Application filed March 3,1902. Renewed October 8, 1906. Serial No. 338,026,

To (LIZ whom it may concern.-

Be it known that I, ROBERT MIEHLE, a citizen of the United States, residing in Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Inking Mechanism for Cylinder-Presses, of which the following is a specification.

This invention relates to mechanism for controlling the rolls whereby the type-forms are inked in that class of bed-and-cylinder presses having a separate set or group of inking-rolls for inking each form.

As usually constructed one roll of each group has not been raised with the others; but I deem it desirable to raise this roll also in the manner hereinafter stated, as thereby a more perfect and even distribution of the ink over the form is obtained.

One feature of my invention is found in the construction of the means employed to operate this roll and also in the improved construction of the devices for liftingthe several ink-rolls at the proper times.

Another feature relates to the provision of means for tripping or lifting the entire group or groups of ink-rolls whenfor any reason that is necessary or desirable.

Still another feature relates to the provision of means whereby both the cylinder and the ink-rolls may be simultaneously tripped or lifted out of action.

The nature of the invention is fully set forth below and is also fully disclosed in the accompanying drawings, in which latter Figure 1 is a partial side elevation of a press embodying my present improvements. Fig. 2 is an enlarged side .elevation of one of the groups of inking-rollers and their immediate actuating devices. Fig. 3 is a longitudinal vertical section of the parts shown at Fig. 2. Fig. 4 is a partial transverse vertical section of the same parts. Fig. 5 is an enlarged partial longitudinal section showing the cam-andlever mechanism for operating the end roller of the group and also the mechanism for tripping all the group. Fig. 6 is a transverse section of the parts-shown at Fig. 5. Fig. 7 is a detail elevation showing the side opposite to that shown in Fig. 5 of some of the parts. Fig. 8 is a section on the line 8 8 of Fig. 2. Fig. 9 isa detail view of one of the roller-bearings. Figs. 10 to 13, inclusive, are diagrams illustrating the operation of the invention. Fig. 14 is a horizontal section on the line 14 14 of Fig. 5.

In said drawings, represents the frame of the press; 21, the reciprocating bed; 22, one of the cylinders; 23 23, the gears on the cylinder-shafts 24 25, the gears for carrying power to the cylinders; 26 26, the typeforms arranged on the bed 21 in the usual manner, one in advance of the other; 27 27, the ink-rolls for distributing the ink on the ink-table; 28, the ink-foiuitain; 29, the fountain-roll, and 30 the transfer-roll.

31 32 33 34 represent two pairs of forminking rolls, each pair being accompanied by a rider-roll 35 or 36 and the two groups forming the ink-applying means of one of the forms. The rider-rolls are provided with actuating-gears 37 and 38, respectively, and these mesh with other gears 39 and 40, which are driven by the rack 41, attached to the reciprocating bed 21, carrying the type-forms and ink-tables.

The rolls 31 and 32 are supported in such manner as to permit their being moved bodily in divergent directions, so they may clear the type-forms as the latter move beneath them at times when no application of ink is desired, and the same is true of rolls 33 and 34. To that end these various rolls are supported as follows: The roll 31, for instance, is supported at each end in an open bearing 42, formed upon one side of a short hollow stud or cylinder 43, sliding in an inclined direction in a stationary block 44. The cylinder is inclined in the proper direction to permit the necessary movement by roll 31 to take place without destroying its contact with the rider 35. The cylinder contains a coiled spring 45, the lower end of which rests upon the closed bottom of the cylinder, and the u per end is confined by a bar 46, secured to tlie block 44 over the open top of the cylinder and over the s ring. The spring normally projects above t 1e cylinder, as seen at Fig. 8, and this permits the latter to move toward the bar 46 until it strikes said bar, and in so doing the spring is compressed. The cylinder is moved to lift the roll by the lever 47 having a set-screw 48 in its vibrating end setting under the lower end of the cylinder'and joined at its other end to the pivoted end of a cam-lever 49 and operated by a top-faced cam 50, the pivotofthe cam-lever being shown at 51. The cam is attached to the type-bed and moved there with and is made sloping at both ends, as plainly shown at Fig. 3, so that it serves to actuate the lever and lift the roll during eachforward and each backward stroke, and so it will allow the roll .to be returned after each raising movement by the spring 45. A binding-screw 480 bears on the set-screw 4-8, as plainly shown. This mechanism is of course duplicated at the other side of-the press.

The roll 32 is provided with bearings like those described, except that they are oppositely inclined, and they are actuated by similar cam-levers 47, having also set-screws 48 and joined to cam-levers 52,.pivo-ted at 53 and actuated by underfaced cams 54, also attached to and moving with the bed. The roll 33 is supported by bearings in all respects like those of roll 31 and actuated by similar levers .47 48, and such levers are joined to cam-levers 55, bearing upon cams 50 and pivoted at 56.

The operation with respect to rolls 32 and 33 is preciselyli'ke that occurring in the case of rol 31 and needs no further explanation, the mechanism acting both :to lift the rolls and allow them to fall at each stroke or movement of the bed in each direction.

In the case of roll 34, which is the roll which in the general construction of these presses has heretofore not been raised, I provide separate means for lifting it above the forms. The bearings of-the roll 34 are similar-to those of roll 32, and it is lifted by similar levers and screws 47 48; but power is communicated to said levers by means different I from those used with the other rojllsto wit, by levers 57 pivoted at 58 and fast to the levers 4 7and said levers 57 are actuated by the following mechanism: Between theouter ends of levers 57 and crankearms '60, which are rigidly mounted upon a rock-shaft 61, extending transversely of the press, are links 59, and secured to this same rock-shaft near one end thereof is a crank-arm 62, pivotally joined to which is a longitudinally-moving bar 63, the farther end of which carries a roller 65, bearing upon the peripheral cam 64, mounted upon a shaft 66. The cam has a raised portion 67 and a depressed portion 68, and when the latter is passing the roller the thrust .of the bar is preferably sustained by the forked end of the lever bearing against the shaft in order that the roller may be easily shifted laterally, as hereinafter stated.

The shaft 66 is constantly rotated by a train of gearing 6.9, 70, 71, '72, and 7 3, of which the gearing 69 is on shaft 66 and 73 on the main shaft 74. The cam'64 is so timed by its arrangement on the shaft as to cause the roller to ride on the raised portion of the cam when the ink-roll 34 is to'be lifted above the forms, such result being .due to the actuation of the bar 63 and the intervening mechanism at such times by the cam and roller.

The mechanism described in the last paragraph serves to raise the ink-roll in question once at each complete forward-and-back movement of the bed while the press is running regularly; but I also provide in conjunction therewith means whereby all the inkrolls in the group or set embracing the roll 34 may be tripped either for a single forwardand-back movement of the bed or for a plurality of such movements, as desired. This mechanism is the following: At 75 is a footlever located conveniently for operation by the attendant and joined at its lower end to an arm 76, rigid upon a rock-shaft 77. This shaft also carries an arm or lever 78, which at its upper end bears against an outstanding horizontal arm 79, supported on a rocking vertical shaft 80, supported in a stationary box or bearing '81. Projecting from the side of shaft is a short rigid arm 82, and riveted to arm 82 is a long blade 8-3, preferably of flexible metal, the outer end of which is placed against the side of roller 65. The cam 64, already mentioned, is formed upon one side of a disk 84, having its periphery partially cut away, so as to form a gap or depression 85, the deepest part of which coincides with the lower part .68 of the cam 64. The gap 85 slopes gently outward at each .of its ends from this deepest part to the periphery of the disk, and a portion 86 of the periphery at the side of the gap is left intact, as plainly shown at Figs. 5 and 6. The roller 65 is free to move laterally on its supportingstud in obedience to the pressure which may be caused thereon by the blade 83, as hereinafter explained, and a spring '87, coiled on the stud, acts upon the roller in opposition to said blade. From this construction it will be seen that the attendant by operating said foot-lever causes the blade-shaft 80 to turn, so as to create pressure by the blade against the side of roller 65, and this pressure will shift the roller over into the gap '85 in the cam-disk as soon as the gap comes in'register with the roller. As soon as the roller is shifted into the gap it rides upon the incline thereof onto the periphery of the disk, and by so doing actuates the bar 63 in the same way as when it rides on the raised portion of the cam but the actuation of the lever is considerably greater in extent in that case and is sufficient to rock the shaft .61 far enough to cause the tripping .or lifting of all the inkrolls. It does this through the arms .60, already mentioned, and the arms '88, projecting from the opposite side .of rock-shaft 61. The arms .60 are connected to levers 57, operating roll 34, as already stated, and are alsoconnected to cam-levers 52 of roll-32 by the rod 89, and the arms 88 are connected IIO to cam-levers 49 of roll 31 and to cam-levers of roll 33 by rods 90 and 91, respectively. The arms depress the cam-levers to which they are joined, as will be understood from the drawings.

The roller when shifted, as already described, may ride on the cam-disk until the depression 85 completes a revolution, so that the roller may reenter it and then be shifted back to its normal position, or the roller may be forced so far onto the periphery of the disk that it will ride upon the rim 86 instead of rentering the depression 85. In the first case the ink-rolls will be relieved from the control of the tripping devices at the end of the revolution of the cam-disk, and in the other case they will be retained in the tripped position so long as the roller 65 is compelled to ride on the cam-disk.

In order to relieve the operator from the necessity of keeping his foot on the footlever until the tripping mechanism has acted or entered fully upon its work, I provide a gravitating-latch 92, stationarily pivoted at 93 and resting upon shifting blade 83. This latch has an offset 94 on its under surface, which when the blade is shifted, as above stated, engages the blade and holds it in its changed or operating position until the projection 95 on the swinging end of the latch encounters the riser or cam 96 on bar 63 and is lifted thereby, so as to free the blade. The latch cannot be thus raised by the riser until the bar 63 has been moved back by reason of the rollers riding on the outer part of the cam-disk, and hence not until after the tripping mechanism has begun to operate, and it will be noticed from this that the operator need not hold his foot on the lever until the tripping action has taken place, because when he depresses the foot-lever he either causes the blade to shift the roller at once or,

if the roller happens to be against the large diameter part of thecam 84 at the time, he stores up power in the blade, which will be retained by the latch until it can be expended in shifting the roller as soon as the gap 85 comes in register, the tripping operation being wholly automatic after the depression of the foot-lever and the blade continuing under tension until the roller enters the gap.

To prevent the spring 87 from forcing the roller back off the camdisk, the restraining power caused by the depressed foot-lever being now withdrawn by the removal of the operators foot, I employ a second latch 97, pivoted to bar 63 at 98 and resting normally at its free end on the hub of roller 65. This latch is adapted to fall between the hub of the roller and the bar 63 when the roller is shifted, and thus serve to prevent the return of the roller under the power of spring 87; but the latch cannot thus act until the bar 63 has moved far enough to clear the latch from the stationary stop-bar 99, located below the latch, and of course the latch will be lifted from its acting position by said stop-bar whenever position of Fig. 5. This latch therefore enters between the hub and bar 63 as soon as the roller is shifted and has actuated the lever and remains in that position until the roller renters the gap 85 in the camdisk and al lows the lever to move back to its starting position.

When the operator desires to retain the rolls in their tripped position during a plurality of bed movements, he either retains his foot on the foot-lever during such movements or he looks the foot-lever down in its depressed position. By so doing the blade retains its pressure against the roller 65 even after the roller has moved onto the periphery of the cam-disk, and thereby shifts it far enough to insure its riding on the rim 86 instead of entering the gap 85. Obviously the roller cannot shift back when it is thus restrained by power from the foot-lever, and consequently the ink-rolls may in this way be held out of action as long as desired.

While the press is running properly and no tripping is desired, I prevent any action by the rods 89, 90, and 91 on the ink-rolls to which they are connected by providing for lost motion between said rods and the respective levers operated by them, as seen at 100.

The ink-roll-tripping mechanism described is preferably connected with the cylindertripping mechanism, and, indeed, the footlever, the lever 76, the cam-shaft 66, and the gears 69, 7 0, and 71 are part of the regular cylinder-tripping mechanism of the press. It will thus be seen that the attendant when he operates the foot-lever not only trips the cylilnder or cylinders, but the ink-rolls as wel 4 In the diagrammatic views, Fig. 10 shows all the rolls as being lowered into bearing contact with the form which they are in tended to ink. Fig. 11 shows the form as having moved away from the first pair of rolls, and that pair is raised to avoid contact with the other form. Fig. 12 shows the form as having moved still farther, and Fig. 13 shows the form as having reached the limit of its stroke and all the rolls as raised.

It will be noticed that the rollers which are supported in bearings 42 have shoulders 102 in contact with the inner ends of the bearings; also, that the supports 43 of the bearings are cylindrical and free to turn in blocks 44 and are located at one side of the plane of the roller-journals. It results from these features of construction that if the rollers have any endwise play or movement such play or movement is liable to cause the bearings 42 and their supports to twist and turn in blocks 44, and thus create unnecessary friction bethe bar 63 returns to the IIC tween the bearings and the journals. To prevent any such endwise play or movement, I provide stops 103 opposite the end of each journal, as plainly shown at Fig. 4. These stops are preferably integral with the blocks 44, by which they are supported, and they are wholly independent of the bearings 42. By thus locating the inclined supports in a plane entirely lateral of the roller-journals instead of a plane coincident with that of the journals I am enabled to give the supports all thelength needed and at the same time gain the needed room at the lower ends of the supports for the adjusting-screws 48 in the ends of the levers 47 and also to avoid any interference witheach other by adjacent and converging levers 47, such as would take place if the supports 43 were in planes concentric with the rollerjournals. This will be best understood from Fig. 2.

The blocks 44 are held in position by the screws 86, and the openings in the blocks through which the screws pass are elongated (see Fig. 2) to allow the adjustment of the blocks in a horizontal direction. The camlever pivots 51 are supported by the blocks and are adjusted, therefore, with them. Spring 101 returns the lever 76 after it has been operated by the foot.
